论文摘要
活性微粒的流体动力相互作用在我们星球的流体环境中普遍存在。因此,了解这些自构粒子的相互作用对于科学和工程至关重要。在本文中,通过扩展了先前开发的随机动力学理论来分析具有多个自旋速度群体的微晶状体和微型运动体的异质集合,从而通过数学建模了活跃的游泳运动员颗粒的悬浮液。本文使用这种建模方法来获取有关活动粒子的悬架不稳定性和空间相关性等大规模特性的见解,并突出了活动粒子旋转对悬架行为的作用。这项研究将着眼于使用数值和实验室实验观察到的分析解释模式形成结果。
Hydrodynamical interactions of active micro-particles are pervasive in our planet's fluid environments. Hence, understanding the interactions of these self-propelled particles is essential for science and engineering. In this paper the suspensions of active swimmer-rotor particles have been mathematically modeled by extending a previously developed stochastic kinetic theory to analyze heterogeneous collections of microswimmers and microrotors with multiple spin velocity populations. The paper uses this modeling approach to derive insights on large scale properties such as suspension instabilities and spatial correlations of the active particles and highlights the role of active particle rotations on the behavior of the suspension. This study will have an eye on analytically explaining pattern formation results observed for self-propelled micro-particles using numerical and lab experiments.
